Abstract
A coaxial connector includes a removable back nut, an outer body, and a center conductor supported within the outer body by a dielectric. The center conductor includes a female socket for receiving an exposed inner conductor of a coaxial cable, and a compression member compresses the female socket to seize the inner conductor as the back nut is secured to the outer body. In use, a prepared end of a coaxial cable is inserted through the back nut, and the end portion of the outer conductor of the coaxial cable is flared outwardly. As the back nut is tightened onto the outer body, the flared end of the outer conductor is directly clamped between integral clamping surfaces of the back nut and outer body. As the back nut is tightened, the compression member simultaneously engages the female socket to seize the inner conductor.
